3. Porewater analysis by DGT/DET/coring
Aim
Interlaboratory intercomparison
identify problems
establish protocol for further work
Methods used
Coring by hand
porewater separation: on field USTL, in lab VUB
cores for DGT and DET transported to the lab
DGT and DET probes deployed at room temperature for 24h (2 cores)
USTL: DGT diffusive gels 0.8 and 1.2mm
in same core
VUB: DGT diffusive gels 0.8 and 0.8mm
in different cores
